The Philippines' new route numbering system, started in 2014, for its network of [[Expressways of the Philippines|expressways]] (limited access roads) and national roads (of the primary and secondary types), uses E and N, respectively. National roads ("N" roads, of the primary and secondary designation) use white shields based on the Australian National Route shields, but signed with the number only, with N included for inventory purposes. Expressways ("E" roads) uses signs the same design as with national primary and secondary roads, but colored yellow, and unlike national roads, includes E to prevent confusion.
